The Vishay SFH6286-4X001 is a 1-channel optoisolator with a transistor output, housed in a 4-SMD gull wing package for surface-mount assembly. Rated for 5300 Vrms isolation, it provides galvanic separation between AC or DC input and the output side, with a minimum current transfer ratio of 160% at 1 mA forward current and a maximum of 500% at the same bias. The output transistor can handle up to 55 V and 50 mA continuous, with a typical Vce saturation of 400 mV at rated conditions.
Switching performance and thermal envelope
Typical rise and fall times are 3.5 µs and 5 µs respectively, with turn-on and turn-off times of 6 µs and 5.5 µs — suitable for low-speed isolation in control and feedback loops where switching rates stay below 50 kHz. Operating temperature spans -55°C to 100°C, covering industrial and some automotive ambient conditions; the forward voltage is 1.1 V typical, and the maximum DC forward current is 50 mA.
Package, compliance, and sourcing posture
Supplied in tube packaging, the SFH6286-4X001 uses the 4-SMD gull wing footprint (supplier device package 4-SMD) — the gull wing leads are visible for solder-joint inspection, a plus for rework and quality screening.
